14 DAY TRIAL // Greg Kroah-Hartman had the pleasure of announcing earlier today, July 1, that the third maintenance release for the current stable 3.15 branch of the Linux kernel is available for download, urging users to upgrade as soon as their Linux distributions update the respective packages on the official software repositories.
Looking through the changelog, we can notice that Linux kernel 3.15.3 is a pretty standard release that introduces various updated drivers, some filesystem improvements, especially for Btrfs and EXT4, random mm and Bluetooth fixes, and the usual architecture enhancements (ARM, ARM64, IA64, SPARC, PowerPC, s390, and x86).
"I'm announcing the release of the 3.15.3 kernel. All users of the 3.15 kernel series must upgrade. The updated 3.15.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.15.y and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary," Greg Kroah-Hartman said in the official release announcement for Linux kernel 3.15.3.
Be aware, though, that upgrading to a new Linux kernel package might break some things on your system, so it is preferable to wait a few days and see if anyone complains about it on the official channels of your distribution.
Linux kernel 3.15.3 was released along with the stable 3.14.10 kernel, as well as the Long Term Supported (LTS) Linux kernels 3.10.46 and 3.4.96. Download Linux kernel 3.15.3 right now from Softpedia.
